Castro Marim Castle
Highlight • Castle
The imposing fortification you can visit today (for a small fee) was built in the 13th century by order of King Dinis, serving as a defensive bastion against invasions and as a watchful sentinel on the border with Spain.
At the top, the reward is a breathtaking panoramic view: the town of Castro Marim at your feet, the shimmering salt flats, the bridge connecting Portugal and Spain, and, in the distance, neighboring Ayamonte.

Forte de Cacela - Largo Ibn Darraj Al-Qastalli
Highlight • Castle
Initially it was under Islamic rule, later, in 1240 it passed to Christian rule.
It has changed over the centuries. In 1755 the earthquake almost completely destroyed it. In 1770 began its reconstruction. Nowadays it continues with the same function, the Fortress is occupied by the Fiscal Guard (GNR) and, for this reason, its interior cannot be visited. The exterior is free and worth the visit, especially the panoramic view over the mouth of the Ria Formosa, which is a beautiful view from this place.

It's definitely worth stopping here, and even taking a break. Unfortunately, the church is often closed, and the "fortress" next to it is also inaccessible.

Castro Marim Castle was strategically built in the 13th century on a hill on the right bank of the River Guadiana. It bears witness to the region's rich military and cultural history. The semi-circular outer wall enclosed the settlement and the so-called Old Castle, and it was here that the town initially developed. Today there are only remains of the castle with four turrets, a gate, the ruins of the 14th-century Church of São Tiago (Saint James), the Palácio dos Alcaides (Governor’s Palace) and houses.
